i noticed that there is a white plug hanging above the left side kicker panel,uder the dash. and i was wondering if i am missing some kind of modual or felay box . i had a thead asking if any one could help me out because my light switch keeps burning out on me. and i need to know if that could be the problem. that box missing i think it has 2 10mm bolts holding it up. thanks for your time jason
